To enhance the water use- efficiency, drip irrigation schedules for mango, guava and aonla have been worked out.
Plastic mulching has proved its efficacy in conserving moisture and enhancing yield of quality produce in mango and guava.
Efficacy of mulching on biological properties of mango and guava orchard soils has been worked out. Variation in leaf gas exchange parameters in plastic mulching in guava and mango has been worked out.
Response of plastic mulching on physiological attributes in relation to nutrient use- efficiency and tree performance has been established.
Plastic mulching has been found to have added advantages of easy tree manipulation for inducing water stress required as a precondition for better flowering. Under these circumstances, the active root zone confined to the top 6-10 inches of soil depth and, therefore, tree manipulation may become easy with drip irrigation.
Profuse flowering under drip and mulching
Technique of wedge grafting has been developed and standardized for rapid multiplication of guava, mango and aonla. This has a tremendous potential for multiplying throughout the year. The technique is well adopted by nurserymen across the country.
Comparative performance of veneer and wedge grafting in mango has indicated superiority of wedge grafting over veneer grafting.
Mass multiplication of guava, mango and aonla through wedge grafting
Comparative performance of budding and wedgegrafting in aonla has been evaluated. Winter months have been found suitable for wedge grafting, while budding gave better success in other months.
Improvement in guava seed germination through plastic mulching
Improvement in rate of seed germination through plastic mulching has been achieved for guava and aonla.
Polyethylene cap has been found instrumental for early sprouting with higher success rate in mango, guava and aonla grafts.
Use of poly cap for early sprouting of grafts
Meadow orchard system has been developed for the first time in guava and popularized in different parts of the country.
Pruning technique has been perfected under high density planting in guava. High density planting has been standardized for guava. Canopy management for sustainable production of quality fruits has been worked out.
Topping and hedging has been found to be a valuable technique in controlling tree size and improving the fruiting potential in guava under high density planting. The yield recorded under high density planting coupled with canoy management are in the range of 40 to 45 tons per hectare without any adverse effect of fruit size, quality and canopy recovery.
Rejuvenation technique for old and unproductive guava and aonla
trees has been developed and standardized with
farmers' participation. It is adopted by National
Horticulture Mission Programme.
